随着科学技术的不断发展,要求机械工业加工的零件形状也越来越复杂。工业产品中。如船用螺旋浆,飞机零件,汽轮机的扭曲叶片,泵叶片,柴油机和汽油机中增压器的导风轮等等,它们的轮廊面都是复杂的曲面。要加工诸如此类的零件,并得到满意的精度和光洁度,靠一般的三座标两联动或三联动数控机床就难以胜任了。为了解决这一 With the continuous development of science and technology, the shape of the parts required to be processed by the mechanical industry is also getting more and more complicated. Industrial products. Such as marine propellants, aircraft parts, twisted blades of steam turbines, pump blades, turbofan turbochargers in diesel and gasoline engines, etc., all of which have complex curved surfaces. To process such parts, and to obtain the accuracy and finish, by the general three coordinate two or three linkage CNC machine is not competent. In order to solve this one
